In this paper, we presented a systematic way for extracting \textsc{SD} based test model for \textsc{SA}s.  We illustrated with a simple, yet representative example of a Bank Application, and provided a transformation schema for mappinf SafArchie \textsc{SA} descriptions into \textsc{SD}s. The use of \textsc{SD} test model is beneficial for sing \textsc{MBT} approaches for \textsc{SA}. We used control and partial data flow analysis for \textsc{SD} test model. In particular, we were able to generate \textsc{ATC}s that serve as a guide for testing actual implementation of the system.

As future work, we plan to automate the \textsc{ATC} generation approach for \textsc{SA}s. This work is in a broader research on testing of  evolving architectures. An architecture evolves in accordance with the structure or the behaviour. Structural evolutions concern the components and connectors, and their underlying constraints, as sketched in the metamodel of Fig. \ref{fig:SAL-MM}. Behavioural evolutions target the operations associated with ports, but also more generally the overall configuration of a system. These modifications not only impact quality of \textsc{SA}s, but also cause significant design and testing changes. In future we will be exploring the use of our proposed work with respect to evolving architectures.

%In this paper, we present a way to use model based testing for software architectures.The detailed use of UML 2.0 Sequence diagram as a test model for software architecture is presented in the paper. We use the test model for control flow analysis. The use of UML based test models for SA based testing is way forward to get benefits for MBT for software architectyres.Moreover the use of Sequence Diagram and an Activity Diagram based CFA opens the way for automation of the work. We present a Banking Case Study as a proof of the concept.The automation of this work and its use in our broader context of tetsing of evolving architecture is a way forward in our research on SA based testing
